evdi 1.8 module not loading in 5.4 kernel?

[5472qaywsx]

Initially please make sure the problem hasn't been already addressed:

• Are you using the latest driver? YES
  (https://www.displaylink.com/downloads/ubuntu)
• Are you using the latest EVDI version? YES
  (https://github.com/DisplayLink/evdi/releases)
• If you are using a DisplayLink device, have you checked 'troubleshooting'
  on DisplayLink's website? YES
  (https://support.displaylink.com/knowledgebase/topics/103927-troubleshooting-ubuntu)
• Is this issue related to evdi/kernel? YES
  (if it is rather connected to DisplayLinkManager please take a look at support
  https://support.displaylink.com or forum https://www.displaylink.org/forum/)

Some information for baseline would help a lot:

• Linux distribution and its version: archlinux
• Linux kernel version: 5.4.57-1-lts
• Xorg version (if used): 1.20.8
• Desktop environment in use: (i3)

$ dmesg | grep -i evdi
[ 11.340401] evdi: loading out-of-tree module taints kernel.
[ 11.340463] evdi: module verification failed: signature and/or required key missing - tainting kernel
[ 11.342528] evdi: [I] Initialising logging on level 5
[ 11.342529] evdi: [I] Atomic driver:yes

Is this something that should be adressed from evdi-side, or something that I should solve specifically on my machine?
There are some comments on archlinux-AUR-evdi page on this.

Cheers,
Dan

It looks like it is loading. The message you are quoting is just an informational message that we all get when running evdi.

Run this lsmod | grep evdi. You should see that the evdi module running.

For example:

evdi                   65536  4
drm_kms_helper        249856  3 evdi,amdgpu,i915
drm                   618496  19 gpu_sched,drm_kms_helper,evdi,amdgpu,i915,ttm

I believe that in order to use evdi 1.8.0, we are waiting on a new release of the DisplayLink driver (https://www.displaylink.com/downloads/ubuntu).

Ok, thank you. You're right about loading.
I will switch back to 1.7.0 and wait for the next release of the displaylink driver.

Any information about release date?

New release date?

Don't want to be rude, but some people are required to use this piece of... software. To make USB-C in any kind a useable standard we NEED working software as a minimun. Lets not repeat the fuck ups of this shitty usb 3 standards.

Hi guys, any news ?

[displaylink-dkurek]

The DLM on the website (5.3.1) contains EVDI v1.7.0 which should be working up to kernel 5.8 (included).
5.9 will indeed need some modifications, but we are currently on v5.9-rc6 so we have around 2 weeks before v5.9 will actually happen. At the moment there is no need to upgrade EVDI to 1.8.0 for DLM :)

Hi ! Thanks for your fast reply, i appreciate. I'm trying to install DLM 5.3.1 but i have this error message :

' sudo LANG=C ./displaylink-driver-5.3.1.34.run
Verifying archive integrity... 100% All good.
Uncompressing DisplayLink Linux Driver 5.3.1.34 100%
DisplayLink Linux Software 5.3.1.34 install script called:
Distribution discovered: "Manjaro Linux"
Unsatisfied dependencies. Missing component: libdrm.
This is a fatal error, cannot install DisplayLink Linux Software.
'

Edit : Of course i tried to install 'dkms' which is present the repositories of manjaro which is not the case of 'libdrm-dev'...

Do you have a work around to fix this issue ?
Thanks in advance !

I've found this topic
https://forum.manjaro.org/t/displaylink-driver-installation-issue/22176
Which describes the same problem. There is AUR package with
DisplayLinkManager 5.3.1 (it's maintained by community).
I'm not familiar with manjaro but it seems it's enough to just call
pamac build displaylink
